Product Description:
LRS switching power supply is also called switched power supply, switching converter, is a kind of high-frequency electric energy conversion equipment, is a kind of power supply. Its function is to convert a level voltage to the voltage or current required by the client through different forms of architecture. The input of a switching power supply is mostly AC power (such as city) or DC power, and the output is mostly a device requiring DC power. LRS series switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrument appearance, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, liquid crystal display, LED lamps, communication equipment, audio-visual products, security monitoring, LED lamp belt, Computer cases, digital products and instruments.
Main circuit impulse current limiting: Limits the impulse current of the input side at the moment when the power is switched on.
Input filter: Its function is to filter the clutter in the power grid and prevent the clutter generated by the machine from reacting back to the power grid.
Rectification and filtering: the AC power supply of the grid is directly rectified into smooth direct current. Inverter: the direct current after rectification into high frequency alternating current, which is the central part of the high frequency switching power supply. Output rectification and filtering: according to the load demand, supply stable and reliable DC power supply. Control circuit on the one hａnd from the output end of the sample, compared with the set value, and then to control the inverter, change its pulse width or pulse frequency, so that the output stability, on the other hand, according to the test circuit supply data, by the maintenance circuit identification, supply control circuit to the power supply for various maintenance measures.
The detection circuit provides the maintenance circuit in operation of various parameters and various appearance data. The auxiliary power supply completes the software (remote) starting of the power supply, and provides power for the maintenance circuit and control circuit (PWM chip) operation.
